Holocene Extinctions and Missoula Flood

“I see from today's news that many people are still confused by the extinctions caused by the Holocene Start Impacts. Its really pretty easy, as Elephants need 450 pounds of food a day.”

Perhaps the following will explain it better. Good hunting, all - E.P. Grondine, Man and Impact in the Americas”

THE WASHINGTON SCABLANDS AND ASSINIBOINE IMPACT ACCOUNTS

Several posters here are interested in Harlan Bretz and the spread of his catastrophist hypothesis for the formation of the Washington scablands. Currently, while all geologistsagree that the scablands were formed by catastrophic flooding, there is debate over whether they were caused by the release of one or multiple lakes and exactly when the flooding(s) occurred.”

The above debate, which mentioned above, is imaginaryin nature. First, the age of the latest Missouri Flood is well established by both radiocarbon dates and well-dated volcanic ash beds from Mt. St. Helens. Wood fragment fromthe lower-middle part of the Missoula Flood deposits in Sanpoil Valley yielded a radiocarbon date of 14,490 14CyrB.P. A 14,000 year old volcanic “set-S” ash from Mount St. Helens overlies at least 28 giant-flood rhythmites and underlies eleven giant-flood rhythmites in southern Washington. Organic matter recovered from within and below the Missoula flood deposits in the Columbia Gorge yielded three dates between 15,000 and 13,700 14Cyr B.P. These and other dates clearly indicate that catastrophic flooding occurred at multiple times during a period of time between 15,700–13,500 14Cyr B.P. (Booth et al. 2004).

The Missoula Flood clearly predate and are, thus, unrelated to any hypothetical terminal Pleistocene or Holocene impact event. As noted above, the Missoula Flood deposits are thousands of years too old to be associated with such an impact. In addition, the detailed study of sedimentology of theflood deposits demonstrates that the catastrophic flooding from glacial Lake Missoula occurred every few decades to years. This is comparable to the frequency in glacier-outburst floods (jokulhlaups) associated with modern Icelandic glaciers (Booth et al. 2004). The occurrence of multiple catastrophic Missoula Flood events over a period of approximately 2,000 years definitely refutes any notion that the Missoula Flood is associated with a single impact event of any age. A single impact would only have created a single catastrophic flood. It would have been quite impossible for a single impact of any age to have created multiple flood events over a 2,000 year period of time as has been well documented in the publishedliterature.

“Of course, as oil companies have for years been drilling cores off the coast of Washington, those questions could be readily answered, except that those cores are proprietary.”

Oil company cores will likely tell use nothing about the Missoula Flood as the deposits that would contain deposits from the Missoula Flood are too young to be of any interest to them. They would simply drilled through such surficial sediments any only start coring once they got to the oil-bearing strata. In addition, petroleum seismic is not designed to image shallow strata, which are of no interest to oilcompanies.

However, research by marine geologists using cores and seismic data have identified and mapped thick turbidite deposits consisting of material from the Missoula Flood that was flushed down the Astoria Fan on the Oregon continental margin. The vast majority of this research, including cores, is not proprietary. This research is discussed in a number of published papers, including:
